1'0 aZZ whom it may concern..-

Be it known that I, PATRICK KENNEDY, a. citizen of the United States,residing in the borough'of Brooklyn, in the county of Kings and city andState of New York, have invented certain new and useful Improvements inInclosing Casings for the Driving-Gears of Car-Dynamos, of which thefollowing is'a specification. V a

This invention relates to means for lightingcars by electricity derivedfrom dynamos driven from the axles of the cars.

In the United States Patent No. 685,516, granted October 29, 1901, on myapplication is shown a dynamo pivotally mounted on the truck-frame of acar and driven from the caraxle bya belt and pulleys, one of the latterbeing on the car-axle and the other on the armature-arbor of the dynamo.The dynamo is, as stated, pivotally mounted on the truckframe and aspring device is employed to so rock the dynamo on its pivot as to keepthe driving belt taut and take up any slack therein.

The object of the present invention is to provide a means for excludingsnow, dust, and the like from the pulleys and belt by which the dynamois driven, so as to preserve the same from undue deterioration and wear.This is a matter rendered the more difficult from the fact thatinrunning,the truck-frame of the car has aconstant vibrating movement withrespect to the axle thereof, and the arbor of the dynamo has also amovement toward and from the car-axle. It is also necessary to providemeans whereby access may be had at all times to the belt and pulleys forinspection. As it is not possible byany known means to wholly excludethe entrance of snow and dust (one or both) to a-protecting-casing aboutthe axle of the car, means are provided 7 herein for expelling orexhausting such snow or dust while-the car is in motion.

In the accompanying drawings, which illustrate an embodiment of theinvention, Figure 1 is a side elevation of the protecting-casing as seenfrom the lower side in Fig. 2 Fig. 2 is a horizontal sectiontaken'substantially along the line 00 in Fig.1. In this view the curedto the upper section.

Serial No. 154,398. (No model.)

belt and pulleys are represented in plan and only the casing 'insection. Fig. 3 is a vertical section taken substantially at 'line m inFig. 2. Fig. 4 is a transverse section at line w in Fig. 1. Fig. 5 is aview of thecast-iron connecting-frame detached.

In the drawings it hasnot been deemed necessary to show the entiretruck-frame of the car, the carwheels, and the dynamo. All

that has been shown aside from the protecting device are the car-axle a,the arbor b of the dynamo, the transverse truck-beam c, a transversesupporting-bar d of the truckframe, the pulley e on the axle, thepulleyf on the arbor of the dynamo, and the belt g on said pulleys.These will sulfice to illustrate the application of the invention inuse.

Theprotecting-casing is of sheet metal stiffened with angle-iron, and itcomprises two sections or parts A and B, which are connected by a frame0, which may be of cast-iron. This frame is shown detached in Fig. 5 andis of rectangular form, with flanges on its faces to enter and formsupports for the sheet metal of the casing. The frame is provided withflanges 72., whereby it is supported on and secured to the truck-beam c.The larger section A of the casing houses the pulley e and 'is in twoparts, the lower portion 2 being removable, while the upper portion 1 isfixed.

This upper portion has a bracket 15, whereby it is supported at one endon the transverse bar 01, while at the other end it is carried on thetruck-beam 0 through the frame O, to which it is secured. The lowersection 2 is fitted up to the upper section, the line of junction beingcovered by a strip or platej, se-

This removable section 2 is secured at its deeper end to the pendentangle-irons 70, Fig. 2, by screws m, and at its other end it is securedto the frame O by screws 'n. It may have handles 0 for holding it whenremoved. The oar-axle a passes through the section A at the line ofjunction of the parts 1 and 2, and where it passes through the sides ofthe casing the latter is provided with dust-guards,of leather or thelike. Each of these dust-guards consists of two like or similar parts19, which are of somewhat conical,or rather semiconical,form. The upperone of these parts p is secured to the upper part 1 of the section A andthe other to the lower part 2 thereof, and their edges overlap, asclearly shown in Fig. 1. The dustguard does not fit snugly about theaxle, but is of such size as to allow the casing to move up and downwithout putting the leather into rubbing contact with the axle, whichwould soon wear it away. These guards do not wholly exclude the dust,snow, or other flying particles, but they aid greatly in keeping theinclosed parts clean.

The section B, which inoloses the pulleyf and forms a continuation ofthe part A, is borne wholly by the frame 0. This section receives thearbor b of the dynamo, said arbor projecting through one side of thesame, as seen in Figs. 1 and 2. As the dynamo has a rocking movement,asbefore explained, the arbor b rotates in a packed aperture in a plateq, which is slidably mounted in keepers 'r on the side 3 of the casing.This-side is fixed to the frame 0 as well as the bottom t. The otherside, 8, (seen in Fig. 2,) as well as the top it and front r, areremovable, being held in place partly by swing-bolts w and w, whichengage slots in the respective ends of a bar 11'' on the front '1}. Theswing-bolt w is hinged to the fixed side 8, and the oppositeswingbolt,w',is longer and extends back to a bracket 10 on the frame C,the bolt being hinged to said bracket. When the nuts on the outer endsof these bolts are loosened, the bolts may be swung out laterally, so asto free the removable parts of the section B. The cover or top plate tois held in place also by screws 203, although there need be. only a fewof these. The pendent flange on the front end of the cover u takes overthe upper edge of the front plate '0, and the two plates are clampedtogether by a bolt and nut 10 the said bolt being attached to the frontplate and engaging an aperture or way in the reinforced flange u on thetop plate or cover.

The object in making parts of the casing interior thereof for inspectionand cleaning.

In spite of all efforts to keep out snow or the like from the casingsome will get in, owing to the necessity for leaving a space about thecar-axle, and such particles-usually snow in winter-ordinarily collectin the end of the casing near the axle (at the left in Fig. 1) and iscarried forward to some extent by the belt g, (to the right-hand end insaid figure.) To remove any accumulation in the casing from the causenamed, the latter is provided at the respective ends of its bottom withejector devices D for exhausting such accumulation when the car is inmotion. This exhauster or ejector device consists of a pendent tube orpipe 1 having in its sides oppositely-disposed openings each providedwith a flared mouthpiece 2. When the car is in motion, the cross-currentof air through the mouthpieces and transversely of the pipe creates apartial vacuum, and the flow of air from the casing carries with it thesnow, dust, and the like.

' The casing will be substantially rectangular in cross-section, as seenin Fig. 4. The truck-beam 0 may be cut away, as indicated in thedrawings, to provide room for the belt should the construction anddisposition of parts require such cutting.

Having thus described my invention, I claim 1. A casing for the purposespecified, comprising the two sections A and B, the former havingdust-guards at its sides and the latter having at one side an aperturedslide to embrace the arbor of the dynamo, and a frame connecting saidsections and having flanges to rest on the transverse beam of the truck.

2. A casing for the purpose specified, comprising the section A, havinga removable lower portion 2, and dust-guards at its sides to embrace thecar-axle, the section B, having a slide at one side to embrace the arborof the dynamo, and a connecting-frame G between said sections andconnecting the same.

3. A casing for the purpose specified, having means for supporting itfrom the truckframe, dust-guards at its sides to embrace the car-axle,an aperture in one side for the passage of the arbor of the dynamo, aslideplate over said aperture and adapted to embrace said arbor, andkeepers for said plate.

- 4. A casing for the purpose specified, having a lower, removableportion 2, apertures in its sides for the car-axle, and dust-guards onits sides, each of said guards consisting of an upper and lower conicalor tapered part1), the upper part being secured to the fixed side of thecasing and the lower part secured to the removable portion 2 thereof,the margins of the partsp overlapping, as set forth. readily removableis to aiford access to the v 5. The combination with the cross-beam Oand transverse bar 01, of a car-truck, of a casing for the purposespecified, comprising the main, or larger section A, the smaller section B, and the frame C secured to the truckbeam 0, said section A beingprovided with a brackett' supported on the bar (lat one end and securedto the frame 0 at the other end, and said section B being provided witha removable side, substantially as set forth.

In witness whereof I have hereunto signed my name, this 24th day ofApril, 1903, in the presence of two subscribing witnesses.
